change amount setting logic

[rlnt]

fixes #6455

This PR changes the behavior of the NumberEntryWidget.

Button Press:
When the current value is 1 and one of the positive amount buttons is pressed, it will use the value of the button without adding the initial value of 1 to it. You will get 100 instead of 101 when you press the 100 button.
I check for % 10 so only necessary buttons are taken into account and to keep the scrolling behavior.

Minimum Changes:
When a screen defines a minimum for the widget, there is now a check if the new value falls below the minimum and will set the new value to the minimum instead. This avoid having negative values or a 0 value in a crafting request sub screen which would block the next button and makes no sense.

I made sure the scrolling behavior, manual adjustment of the value and all the buttons still work.
Here is a video of the new behavior.
